transversely of the plate D centrally between two seat-forming lugs cl, with which the outer side of the said plate is provided and. which project laterally and outwardly from the said plate. The lugs (Z are arranged in the same 55 or approximately same plane horizontally.

A detent-bearing plate K is l'GlllOVi bly secured by means of screws f to the jamb G externally of and next adjacent to the doorway at the outer side of the doorway. The latch 60 G in its operative position, as shown in solid lines, Figs. 1 and 3, when the door A is in its closed position extends across the outer side of the plate K. The latch G is provided at its free end with two projections 6 and 7, ar- 5 ranged at the top and bottom, respectively, of the latch. The lower projection 7 depends from the latch and in the operative position of the latch and as shown in Figs. 1 and 3 overlaps the outer side of a vertically-arrangec 7 detent-forming lug 7'2, with which the plate K is provided. The lug 7: is therefore a stationary detent arranged to retain the latch in its operative position in the closed. position of the door, and in the said position of the latch the 75 upper projection 6, which points upwardly, is overlapped at its inner side by a movable detent R, which is pivoted, as at 0', horizontally to the plate K and arranged to swing in a vertical plane with the pivotal bearing of the de- 30 tent R parallel with the pivotal bearing of the latch G, so as to render the said detent it ca- To all whom, it may concern.-

Be it known that I, PATRICK J. CAssnnLY, a citizen of the United States of America, residing at Elyria, in the county of Lorain and State of Ohio, have invented certain new and useful Improvements in Fasteners for Sliding Doors, and I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to IO which it pertains to make and use the same.

This invention relates to improvements in fasteners for the sliding doors of freight-cars and warehouses.

The object of this invention is to provide a 5 fastener of the character indicated which is simple and durable in construction and not liable to get out of order.

With this object in view my invention consists in certain features of construction and combinations of parts hereinafter described,

and pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a portion of a sliding door and door-casing and illustrates a fastener em- 5 bodying my invention. Portions are broken away in this figure to reduce the size of the drawing. Fig. 2 is a vertical section on line 2 2, Fig. 1, looking in the direction indicated by the arrow. Fig. 3 is a top plan in horizon- 3 tal section on line 3 3, Fig. 1. Fig. t is aside elevation, largely in section, illustrative of the operation of my improved fastener in actuating the door from an open into its closed popable of being swung by the said latch during sition. Fig. 5 is a section taken vertically the movement of the latch endwise with the 3 5 through an end of the latch-plate of the fasdoor in actuating the door from its open into 5 tener. its closed position.

Referring to the said drawings, Adesignates By the construction heretofore described it a sliding door which engages at the top and will be observed that the latch in its operabottom with parallel horizontally-arranged tive position when the door is closed is deslideways 7), formed in the casing 13, and C tained from above by the movable detent 1t 9 represents a jainb of the door-casing. In Figs. and from below by the stationary detent I and 1, 2, and 3 the door A is shown in its closed that the said latch rests upon the one or the position. other of the lugs (Z, according as the latch is The door A is provided at one side and at the in its operative position (shown in solid lines,

. side of the said doorby screws 6. The plate 1) is The latch-plate D is provided at each end provided at its outer side with a latch G, which and upon its outer side with a slight convexis capable of being swung in a vertical plane, ity or swell 8, as shown in Figs. 1, 3, and 5,

5 being pivoted, as at H, horizontally to and and the outward swell 8 of the one or the other end of the said of the latch, according as the latch is in the one or the other of its positions, and holds the latch far enough from the outer side of the said plate to avoid material interruption to the flow of water adown the said plate during rain or at any other time and to reduce the liability of the latch becoming rusted to the latch-plate to a minimum. The outer end of the latch is provided with two inclined edges 16 and 17, which slope outwardly and toward each other from the extremities of the projections 6 and 7 of the latchthat is, the said edges diverge inwardly and meet centrally of the outer extremity of the latch. It will be observed, therefore, that the upper inclined edge 16 slopes upwardly and inwardly to the upper extremity of the upper projection 6 and the lower inclined edge 17 slopes downwardly and inwardly to the lower extremity of the depending projection 7.

During the actuation of the door from an open into its closed position the lower inclined edge 17 comes, as shown in Fig. 4, into engagement with the stationary detent is and is acted upon by the said detent in the direction required to lift the latch and enable the lower projection 7 to pass over the said detent. Also during the actuation of the door from an open into its closed position the upper inclined edge 16 comes into engagement with the movable detent R, as shown in Fig. 4, and swings the said detent outwardly to permit the upper projection 6 to pass in under the said detent, and the said projection 6 has its inner side sloping downwardly and inwardly toward the axis of the latch to accommodate the swinging of the said detent R into an inoperative position, and the said detent is provided with arms 10, at which it may be conveniently taken hold of in rendering the same inoperative.

The plate K is provided also with a seal-receiving member 12, which bridges the path of the latch G at the outer side of the said path, and the said member 12 is provided with a lateral perforation 13, arranged to register with a lateral perforation 14:, formed in the free end of the latch when the latch is in its operative position and held to the said plate by the detents, and the said perforations accommodate the application of a seal S. (Shown only in Fig. 3.)

What I claim is l. A fastener for asliding door, comprising a latch pivoted to the latch-plate and provided, at its outer end, with two projections formed at the top and bottom respectively of the latch, which latch has also two inclined edges which are formed upon the outer end of the plate engages the inner side latch and diverge in the direction of the inner end of the latch; a latch-plate adapted to be secured to the door and provided upon its outer side with a lug arranged to form aseat for the latch upon swinging the latch from its operative into its inoperative position; a

detentbearing plate adapted to be secured.

to the door-casing and provided with a cletent-forming lug arranged to overlap the inner side of the lower projection of the latch in the operative position of the latch when the door is closed, and a movable detent free to swing in a vertical plane and pivoted to the last-mentioned plate, which detent has its pivotal bearing parallel with the pivotal bearing of the latch, and the said last-mentioned detent being arranged to overlap the inner side of the upper projection of the latch in the operative position of the latch.

2. A fastener for asliding door, comprising a latch-plate adapted to be secured to the door and provided upon its outer side with two outward swells arranged at opposite ends re spectively of the plate, said plate also having two seat-forming lugs arranged a suitable distance apart between the aforesaid swells and in the same or approximately same plane hori zontally; a latch pivoted to the latch-plate centrally between the two seat-forming lugs, and a plate adapted to be secured to a door-casing and provided with means instrumental in retaining the latch in an operative position, and the arrangement of the parts being such that the latch has bearing on the one or the other of the aforesaid seat-forming lugs according as it is in its operative position or has been swung in its opposite and inoperative position.

3. A fastener for a sliding door, comprising a latch-plate adapted to be secured to the door and provided upon its outer side with two seat-forming lugs arranged a suitable distance aparthorizontally; a latch pivoted to thelatchplate between the two seat-forming lugs, and a plate adapted to be secured to a door-casing and provided with means instrumental in retaining the latch in an operative position, and the arrangement of the parts being such that the latch has bearing on the one or the other of the aforesaid lugs according as it is in its operative position or has been swungin its opposite and inoperative position.

In testimony whereof I sign the foregoing specification, in the presence of two witnesses, this 9th day of June, 1903, at Cleveland, Ohio.
